ANTCREEPER TIE PLATE.

Application filed November 29, 1922.

To all whom t may concern.

Be it known that l, Bntwmirx L. CLEVE- LAND, a citizen of the UnitedStates. residing at Chattanooga, in the county of Hamilton and State ofTennessee, have invented certain new and useful lmprovememts inAnticreeper Tic Plate; and l do hereby de-.

clare the following to be a full, clear and exact description of thesame, reference being had to the accompanying dra-wings,

forming part of this specification.

This invention relates to devices for holding railroad rails on theusual ties, as well as for preventing the creeping of the rail in alongitudinal direction,

The principal object of the present invention is to provide in a singledevice means for holding the gage and preventing the creeping of therail. Ai further object of the present invention is to provide atwopiece anticreeper tie plate. @ther and further objects of the presentinvention relate more particularly to the various details ofconstruction as pointed out in the claims hereafter.

lt is customary at the present time to use certain tie plates and otherdevices for holding a railway rail to the cross ties and it is also oldto use in combination with these 30 devices for preventing relativelateral movement of the two rails other means for preventing alongitudinal movement or creeping of the rails. ln the device formingthe subject matter of the present invention these two means are combinedin a single device consisting of two parts which mutually cooperate toprevent creeping, each of the elements at the same time acting as a tieplate.

In the drawings,-

Figure 1 is a plan view of a preferred form of the present invention.

Fig. 2 is'an end view thereof.

Fig. 3 is a section taken on the line 3--3 of Fig. 1.

Fig: 4 is a similar view to Fig. 3 but showing the modication.

The larger of the two members numbered 10 in the drawings may beconsidered as being the tie plate proper, in its preferred form being arectangular frame having an oblong centralhole 11 to receive thesomewhat smaller cooperating tie plate 12. The larger tie plate 10 isprovided with two or more spike receiving openings 14 to receive SerialNo. 603,983.

the usual railroad spikes 15 and in accordance with the form of spikeused are either rectangular as snown or round or oval if' spikes of thatnature are used. At one end of the larger member 10 are located aplurality of jaws 1"? each preferably reinforced by a number ofstiflening ribs 1S so that considerable strength without excess weightmay be secured.

At the opposite end of the larger member 10 and preferably staggeredwith relation to .the jaws 17 is a small transverse rib or backing post20 stiffened like the jaws iT with a. plurality of stiffening ribs 21and having a relatively steep inclined portion 22 extending from the topof the backing post to the lower surface of the tie plate. The inclinedsurface 22 may be smooth, toothed, or corrugated, the latter form beingpreferred and hence illustrated.

The smaller cooperating tie plate is provided with a single jaw 25 withstiffening ribs 26 corresponding in size and shape to the jaws 17 andribs 18. At the rear end of the jaw 25, however, the smaller tie plateis shortened by a beveled surface 27 adapted to cooperate with theinclined surface 22 and similarly finished, that is, if the surface 2.2is smooth, it is best to have the surface QT smooth also and in thepreferred type since the incline 22 is corrugated the cooperatingsurface 27 of the smaller tie plate is correspondingly corrugated. Likethelarger tie plate the smaller tie plate 12 is provided with one ormore holes 30 similar in size to the holes 14 and for the same purpose.it is to be understood that while l have shown two jaws and two holeslll in the larger member and a single jaw and a` single hole in thesmaller member, the invention in-v i 1 Lt 5) cludes obvious changes, forexampleY by providing a number of jaws or holes or both in the smallermember and by having for example a single jaw on the larger member and aplurality of spacing barking posts.

ln the modification shown in Fig. l. for the jaw 25 l substitute a muchlarger jaw 39v having a` notch 33 to receive the base flange 341 lof therail and extending up into contact with the inclined surface of the rail36 to aid the thin web 37 in supporting the rail heads to maintain moreeffectively the gage. Except for the enlargement of the jaw to form arail head support, the device shown in Fig. 4 is similar to the simplerconstruction shown in the otherl three figures. In operation the smallertie plate 12 is slipped on the rail and the larger plate is then broughtinto Contact first with the free base flange and then revolved aboutthis as a pivot until the end of the frame swings into contact with theinclined surface 27. The two members as a unit are neXt shifted ifnecessary into exactposition and the rail lowered against the tiewhereupon the larger member 10 is spiked down by means of the members 15passing through the holes 14. The smaller tie plate 12 is then hammeredinto position by blows upon the jaw 25, after which this tie plate isspiked into place. It will be noted that vertical p-ressure applied tothe head 36 and transmitted through the web 37 and base flange 34 willtend to move the smaller member 12 downwardly and this action by virtueof the contact between the inclined surfaces 22 and 27 will cause thetwo tie plates to approach each other so as to bite the rail. This willentirely eliminate all possible creeping as during the time the rail ismost stressed it is also most. closel)7 held against longitudinalmovement. 'By providing the inclined surfaces 22 and 27 withcorrugations of very slight depth the downward movement of-the railunder the weight of a train not only draws the two tie plates togather,but leaves them locked after pas-sage of the train.

lli/hat I claim is: s

1 In combination, a tie plate having a rectangular central opening, aplurality of jaws on said plate, a backing post rising from said tieplate opposite and staggered with respect to said jaws and having acorrugated inc-lined surface facing said jaws, a second tie plate havinga rail engaging jaw and having the rear end of said jaw corrugated tocooperate with the inclined surface 0f said backing post.

2. An anti-Creeper tie plate consisting of two flat bottomed railsupporting members provided with cooperating inclined fac-es each ofsaid members having a rail flange engaging aw, the jaw of one of saidmembers extending upwardly to engage and support the head of the rail.

3. In combination, a tie plate consisting of a flat plate having arectangular opening therein, one of the lesser sidesr of saidrectangular opening being bounded by a roughened inclined face, acooperating inner tie plate fitting within said rectangular opening andhaving a roughened inclined face cooperating with the similar face onthe outer tie plate and a rail receiving jaw on eachV of said members. f
